The contact owns a 2012 Chevrolet Malibu. The contact stated that while driving approximately 60 MPH and following a slight right turn on the highway, the ESC warning illuminated, and the vehicle slowed down without the brake pedal being depressed. The failure was intermittent but became a recurring failure. The contact stated that the vehicle also slowed down unintentionally while making a left or right turn at slow speeds. The contact stated that in the middle of the turn, the vehicle slowed to a stop without the brake pedal being depressed. The ESC warning light illuminated while the vehicle was still in drive(D) and running. The vehicle came to a stop, and the accelerator pedal was depressed, and the vehicle continued driving. The vehicle was taken to a local dealer and was diagnosed with PSCM failure. The vehicle was repaired; however, the failure reoccurred. The vehicle was not taken back to the dealer. The contact researched online and related the failure to NHTSA Campaign Number: 14V252000 (Electrical System, Exterior Lighting, Vehicle Speed Control, Electronic Stability Control (ESC). The manufacturer was not informed of the failure. The failure mileage was approximately 166,000.

Rear windowed defroster suddenly start working upon inspection the rear electrical block that's inside the trunk had melted in the fuse to the defroster had gotten stuck and went on pulling it out it broke and after looking up complaints it seems to be an issue with Malibu and it could cause a fire but GM is doing nothing about it you have to pay for it yourself they released a bulletin to bypass the block but you have to install a whole new block which costs hundreds of dollars

First, there is a problem with the transmission. The car will stall or stop abruptly while driving. Second, the automatic turn signals do not work. Third, the driver safety belt does tightly secure the driver.

Electrical problem causing the passenger side low beam to keep burning out. Fourth time in one year. Vehicle is available for inspection upon request. This issue causes a safety concern because you can be driving down the highway at night and all of a sudden you have no headlight.

Passenger and or driver side low beam headlight continues to go out. Mechanic has found connector keeps burning out the socket. Light is fine but connector is shorting out. Fire and safety issue. This issue is on a lot of chevrolet malibu and needs a recall fix.

Passenger side headlamp burned out took off bumper to inspect and the wiring pigtail to the headlight has melted causing it to malfunction so now in order to make it work you have to disconnect the daytime running lights so that the melting stops this is supposedly happened to a lot of Malibu's why there isn't a recall on this fire hazard is beyond me and it is a safety issue cuz you can't use your daytime running lights any longer. This issue has not been reported because upon investigation it's been reported many times and nothing gets done about it you have to pay for it yourself. This will be the last GM product.

The front exterior low beam bulbs / wiring harness keeps burning out. I have replaced them twice already and they have blown again. What is going on already a headache just to even get to the headlights, now have to spend MORE money to repair.

Vehicle will intermittently not start, have to tap on trunk fuse box to get the Malibu to start, the wire is too small and burns up, can’t find anyone to replace it, is a big issue with this generation of Malibu. Vehicle has shut off while on highways and stoplights on MULTIPLE occasions

My brake lights constantly go out. My fuses keep blowing. Every time I try to adjust my mirrors the fuses blow for the mirrors and brake lights. Also my headlights keep blowing and the headlight harness has been changed and everything. It is very dangerous not having brake lights, or being able to adjust my mirrors.

The wiring to the fuel pump overheated and burned at the rear fuse box located in the trunk, melting the harness connector and charring the fuse box circuit board. This caused the vehicle to stop running. Luckily, it happened while idling and did not start a fire. This wire goes to the fuel tank and the fuse did not blow. The 30A fuse for the RR DEFOG was also burnt and not blown.There were no warnings or engine codes. After researching this online, it appears it is a common problem. This is the second time this happened. It also happened in 2017 with approximately 89,200 miles.

The contact owns a 2012 Chevrolet Malibu. The contact stated while driving at 40 MPH the traction warning illuminated. The contact stated that the ABS and the traction control were disabled. The contact stated that the failure was occurring at any speed. Additionally, the contact stated that the brake lights were randomly illuminating when he depressed the brake pedal. The contact stated that he had to depress the brake pedal with force for the brake lights to illuminate. The contact had taken the vehicle to an independent mechanic was diagnosed and determined that the vehicle needed to have all four brake pads and rotors replaced and two front tires replaced. The vehicle was repaired, however, the failure reoccurred. The manufacturer was not informed of the failure. The failure mileage was approximately 103,000.

The brakes light keep going out they won’t blink the won’t turn on fuses are blowing

Since day one the ESC - Electronic Stability Control has constantly affected the performance of the car. The car is not able to reach its full power and causes sudden speed changes . This has happened for a long time with no fix

Passenger headlight caught fire while driving

Passenger side low beam headlight wont work. Replace fuses relays and wiring harness. Ive read online where this is very common with these cars and even replacing the headlight assembky isnt a sure fix.

Passenger headlight continues to go out, replaced bulb and wiring harness multiple times

The headlights keep.going out. I've replaced everything amd it keeps happening and it's not easy to even get to the headlight. This is a hazard as my 16 year old drives this car. We fix it and then it's out all.over again. This has to be a recall as I've done some research and im.not the only one with this problem. We've been pulled over and we just explained our frustration and they've been nice enough to send us on our way.

Vehicle has intermittent periods where it won’t start. After replacing fuel pump relay it started after a week vehicle stalled while driving tested relay worked perfect after reading online forums found that this model car has an issue with the wiring to the fuse/fuse block in the trunk after pulling the fuse block out the wiring to the block is loose and very thin after adjusting the wires the car will start and run with no issues for several days to week where it will be fine the the wires will come lose again causing a crank. I start issue and stalling while driving.

Vehicle repeatedly shuts down due to wiring issue for fuel pump. Wire in rear fuse panel (in trunk) shows signs of overheating (discoloration). Vehicle shuts down without warning while driving. This causes an unsafe condition especially when travelling on busy roadways and highways. This seems to be a common problem with this model and year.
